T1-2: Exploring and Changes in Matter
The simplest form of matter.
What is an atom?
Oxygen and nitrogens are both examples of this.
What are elements?
This type of bond has metals and non-metals.
What are ionic bonds?
iron + oxygen → iron (III) oxide
shows this type of chemical reaction.
What is a formation reaction? (Or what is formation?)
In WHMIS, the flammable symbol looks like this. (draw on the board)
What does a flame over a line mean?
Solubility, luster, and conductivity are all examples of this type of property.
What are examples of physical properties?
What are neutrons, electrons, and protons?
This is the IUPAC name for FeO. (remember to think about the fact that iron has two different charges, (II) or (III)!)
What is the chemical formula for iron (II) oxide?
Photosynthesis is an example of this type of reaction that absorbs heat.
What is an endothermic reaction?
In WHMIS, the biohazardous symbol looks like this. (draw on the board)
What does a black circle with three semi-circles in the middle, all facing outwards mean?
Chocolate chip cookies are an example of this type of mixture.
Ca, Co, Au, and Ag are all examples of this.
What are metals? (or what are transition metals)
This is the chemical formula for beryllium chloride.
What is BeCl2 ?
Cellular Respiration is this type of reaction that releases heat.
What is an exothermic reaction?
This type of change makes the substance change in form but not in chemical composition.
What is physical change?
Two main points of this are:
All matter is made up of extrememely tiny particles.
Particles are always moving
What is the particle model of matter?
Lithium and potassium are examples of this type of family in the periodic table, which are highly reactive.
Neon and argon are examples of this type of family in the periodic table, which are non-reactive.
(You must list both families to get the points.)
What are examples of alkali metals?
What are examples of noble gases?
The IUPAC name for CCl4.
What is carbon tetrachloride?
This is how fast reactants complete their chemical reaction.
What are reaction rates?
The IUPAC name for this compound is dinitrogen pentoxide. (just name the element in chemical formula form using "what is")
What is N2O5?
This type of mixture are generally look like one product and are unfilterable.
What are solutions?
This law states that mass cannot be created or destroyed.
What is the law of conservation of mass?
Low melting point and lack of conductivity shows that it would most likely be this type of compound.
What are some shared properties of molecular(covalent) compounds?
Cooling down the temperature of reactants and its surface area achieves this. (answer by starting with how)
How can you slow down reaction rates?
In a reaction with a compound and a lone element, one element is a compound is replaced by the lone element.
What is a single replacement reaction?
